Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731588, here are decompositions:

17 + 8731571 = 8731588
59 + 8731529 = 8731588
311 + 8731277 = 8731588
401 + 8731187 = 8731588
449 + 8731139 = 8731588
479 + 8731109 = 8731588
491 + 8731097 = 8731588
557 + 8731031 = 8731588

Showing the first eight; more decompositions exist.
